Gunjan,

Are you using your own version of VirtualBox, with freesurfer installed
on it by you? Or the VirtualBox version of freesurfer made by us and
downloaded from our website? I am confused because in your email below,
freesurfer appears to be installed on the Desktop whereas the
prepackaged version made by us is installed in /usr/local
